1 Introduction

Dental electric motor for driving dental handpieces for dental

surgery, Mainly used for dental aesthetics restoration, crown breaking,

open marrow preparation, deburring, polishing and other aspects of

power.

1.1 Precautions before operation

Dangers

1. To prevent electric shock, do not use a wet hand to pull the power

cord, and please prevent the water from entering the control circuit.

Keep away from explosives and ammable materials. Do not use

this dental electric motor for patients who are anesthetized with nitrous

oxide.

Warnings:

1. This dental electric motor may malfunction when used in an

environment where electromagnetic interference occurs. This dental

electric motor cannot be installed near the device that releases the

magnetic wave. When using an ultrasonic vibrating device or an

electrode knife in the vicinity, turn o the switch on the dental electric

motor control panel.

2. MT2 requires special precautions for EMC and needs to be

installed and put into use according to the EMC environment.

3. Device with electromagnetic transmitting will aect the normal

operation of MT2. Please do not run both devices at the same time.

4. Do not use it in operating rooms that contain a mixture of

potentially ammable gases.

5. To avoid possible injury or damage to the dental electric motor,

make sure that the motor handpiece (hereinafter referred to as the motor)

is completely stopped when changing the contra-angle. (And the contra-

angle tool should be replaced by the pedal controller.)

6. A severe impact, such as a drop from high position, can result in

damage to the dental electric motor.

7. Do not try to disassemble the controlling penal or motor.

8. After use, please immediately clean, lubricate and disinfect the

dental handpiece (hereinafter referred to as the handpiece).

9. Do not lubricate the motor. The lubricant can cause overheating

and damage the motor.

10. Do not use a solution with dissolving ability to clean the control

panel.

11. Do not remove the motor cable from the motor.

12. After each operation, turn o the power supply.

1.2 Intended use

Provide driving force of dental handpieces for dental surgery.

6 Safety precautions

Cautions

6.1 For repairs and purchase of spare parts, please contact our

authorized supplier.

6.2 The accuracy of the speed monitoring depends on the high-

precision performance of the handpiece installed on the micro motor. If

the handpiece of other manufacturers is used, the actual speed value may

not be displayed correctly. To ensure the actual matching display speed,

please use the matching handpiece.

6.3 Read this operating manual before use and fully understand the

functions of each part.

6.4 Check the operating status of the dental electric motor before

use to conrm that there is no abnormality.

6.5 Test the dental electric motor before use to ensure accurate

operation.

6.6 If the dental electric motor is permanently malfunctioning

(excessive vibration, noise and heat generation, etc.), please immediately

close it and return it to the authorized dealer.

6.7 Clean the control panel with a damp cloth and turn o the power

before cleaning.

7 Cleaning, disinfection and sterilization

7.1 Cleaning

Cleaning the motor surface with a water-absorbent cloth to remove

any liquid residue from the motor surface and wipe it back and forth 5

times.

7.2 Disinfection

Use a chlorine-free disinfectant to wipe the motor. It is

recommended to use Cavicide disinfectant or 75% alcohol, but do not

soak the motor in the disinfectant.

7.3 Drying

Drying should be conducted after cleaning and disinfection. It is

recommended to use compressed air to dry.

7.4 Sterilization

Before sterilization, first remove the motor, install a sterile plug

and a sterile aluminum sleeve, place the motor in a high pressure steam

sterilization bag, and seal it. And then sterilize it under the temperature

and pressure of 134 ° C (273 ° F) and 2.0 bar ~ 2.3 bar (0.20MPa

~ 0.23MPa) ) for not less than 4 minutes. Drying is needed after

sterilization, The sterilization of the dental contra-angle handpiece is

detailed in the instruction manual of the contra-angle handpiece.

Warnings:

1. Install disinfection plug and disinfection aluminum sleeve at the

motor interface before sterilization. The installation method is shown

above.

2. Before sterilization, the tail cord should be removed.

3. Do not lubricate the inside of the motor.

4. The motor can be sterilized repeatedly for at least 250 cycles of

sterilization.

5. Except the motor and contra-angle, the other parts such as main

unit, power adapter and tail cord are not allowed to be sterilized.
